How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to keep your ears open to traffic, bells and the people around you while you listen, choose GZCRDZ Air Conduction Open; if you need a traditional over-ear headphone with a full-size driver and a tangle-free cable for long desk and travel sessions, choose Botesty Sound Headphones.
• GZCRDZ Air Conduction Open — biggest strength: an open-ear hook design that sits on the outer ear so you still hear your surroundings, in a body that weighs around 18g and carries an IPX4 rating for rain and sweat.
• GZCRDZ Air Conduction Open — biggest trade-off: it is wired only (3.5mm), has no active noise control, and an open design by nature lets outside sound in — that is the point, but it also means no isolation when you want quiet.
• Botesty Sound Headphones — biggest strength: a 40mm dynamic driver in a full over-ear cup, a 4.9ft nylon braided tangle-free cord, and passive noise cancellation from the closed cup.
• Botesty Sound Headphones — biggest trade-off: no on-headphone volume control, no 3.5mm jack on some modern phones without an adapter, and the mic is not supported on desktops and certain laptops.
• Pick GZCRDZ Air Conduction Open if you run, cycle, commute on foot, or need to stay aware of your environment.
• Pick Botesty Sound Headphones if you want a standard over-ear listen at a desk, on a plane, or on a laptop/tablet with a proper 3.5mm port.
The GZCRDZ Air Conduction Open is built around a single idea: don't seal the ear. The earpiece rests on the outer ear rather than inside the canal, so music plays while ambient sound still reaches you. The manufacturer describes it as an open design for hearing traffic coming or a ringing bell while running, cycling or driving. If you've ever pulled an earbud out at a crosswalk just to check what's behind you, this is the category of headphone built to remove that step.
Who should buy it: runners, cyclists, walkers, commuters who cross streets, delivery riders, and anyone doing online classes, live broadcasts or study sessions who needs to hear their own voice and the room. Who should skip it: anyone who wants to block out a noisy office or a plane cabin, anyone who needs wireless, and anyone who wants deep bass from a large driver — a 16mm open earpiece is not that product.

Botesty Sound Headphones: Who It's For
The Botesty Sound Headphones go the other direction entirely: a conventional over-ear, closed-back wired headphone. The driver is 40mm — a full-size dynamic unit — with impedance rated at 40Ω, sensitivity at 110dB and a frequency range of 20Hz to 20,000Hz. That's a heavier electrical load than the GZCRDZ, but still within reach of a phone, tablet or laptop headphone jack. The over-ear cup with a circular earpiece shape encloses the ear and delivers passive noise cancellation, which is the honest way of saying the cup physically blocks some outside sound rather than cancelling it electronically.
The cable is the standout detail: 4.9ft (1.5m) of nylon braided cord, described as tangle-free. That extra length over the GZCRDZ's 1.3m matters if your laptop sits across a desk or your seat-back screen is a stretch away. The finish is blue plastic, and the package includes a user manual. Warranty is listed at 3 months.
The manufacturer is unusually upfront about the caveats, and you should read them before buying: volume can only be adjusted on the connected device, not on the headphones themselves. Any device without a 3.5mm jack needs a conversion adapter. And the microphone is not supported on desktops and certain laptops. If you plan to take calls from a desktop PC, that last point is close to disqualifying.
Who should buy it: students, office and library listeners, air travellers, and anyone with a tablet, laptop, MP3/MP4 player or older phone that still has a 3.5mm port — and who wants a longer, tougher cable and some physical isolation from the room. Who should skip it: phone owners without a headphone jack who don't want an adapter, desktop users who need the mic, and anyone who wants on-cable volume control.
• Best for staying aware of traffic and surroundings → GZCRDZ Air Conduction Open. The open-ear fit is designed precisely for this.
• Best for blocking out a noisy room → Botesty Sound Headphones. The closed over-ear cup provides passive noise cancellation; the GZCRDZ has none.
• Best for long cable reach → Botesty Sound Headphones. 4.9ft of nylon braided cord versus 1.3m on the GZCRDZ.
• Best for sweat, rain and sport → GZCRDZ Air Conduction Open. IPX4 plus an 18g body and ergonomic earhooks.
• Best for hands-on controls → GZCRDZ Air Conduction Open. It has an inline remote for playback, volume and calls, plus a mic mute button. The Botesty has no on-headphone volume control at all.
• Best for taking calls on a laptop → GZCRDZ Air Conduction Open, since the Botesty mic is not supported on desktops and certain laptops.
• Best for big-driver sound from a full cup → Botesty Sound Headphones. 40mm dynamic driver versus a 16mm open earpiece.
• Best for plug-and-play simplicity with no adapter worries → depends on your device. Both use 3.5mm, but the Botesty explicitly notes that jackless devices need an adapter, and it asks you to check before use.
In my opinion, the deciding question isn't sound at all — it's whether you want your ears open or closed. If you're buying for movement, the GZCRDZ Air Conduction Open is the one I'd pick: the open-ear design, 18g weight, IPX4 rating, inline controls and working mic make it the more versatile everyday headphone for running, cycling and commuting, and it's the only one of the two with on-cable volume and a mute button. I'd only choose the Botesty Sound Headphones if your listening happens sitting still — desk, library, plane — and you specifically want a closed cup with a 40mm driver and a longer tangle-free cable, and you've confirmed your device has a 3.5mm jack and that you don't need the mic on a desktop.
No. It's a wired 3.5mm headphone with a 1.3m cable. There's no Bluetooth on it, so it works with anything that has a standard 3.5mm jack.
They have passive noise cancellation, which comes from the closed over-ear cup physically blocking outside sound. There's no active noise cancelling electronics, and no battery involved.
No. The manufacturer states volume can only be adjusted on the connected device. If on-cable volume matters to you, the GZCRDZ is the better fit.
The GZCRDZ Air Conduction Open. Its open-ear design keeps you aware of traffic and bells, it weighs about 18g, and it's rated IPX4 for rain and sweat. The Botesty is an over-ear cup intended for seated listening.
